mon·o·type

Monotype is a medium wherein the artist manipulates ink on a metal plate and then runs it through a printing press, resulting in a single impression.

mon·o·typeˈmänəˌtīp/noun

The image is transferred from the plate onto a sheet of paper by pressing the two together, usually using a printing-press.

Monotypes can also be created by inking an entire surface and then, using brushes or rags, removing ink to create areas of light from a solid area of opaque color. A monotype impression is usually unique, though a second, lighter impression from the painted printing plate can sometimes be made.
